Specification of Letters Patent. Pgatgntgd Apr gg, 1913,,

Application filed October 6, 1917. Serial No. 195,132. I

To all whom it may concern:

Be it known that I, OSCAR I. HnNsnnn, citizen of the United States of America, residing at Mekinock, in the county of Grand Forks and State of North Dakota have invented new and useful Improvements in Churns, of which the following is a specification.

This invention comprehends generally improvemcnts in that class of inventions known as agitating and more particularly has reference to a churn.

.It is the primary aim and object of this invention to provide a device of the above character wherein the construction is of novel form to assure of an effective operation of the various parts which incidentally are designed so that they may be readily disassembled and cleaned.

More particularly the present invention embraces the provision of a churn wherein improved means is employed for guiding the movement of the pistons or plungers when in operation. I

As a further improvement this invention contemplates the provision of a device of the above mentioned character designed. so

that all of the operating parts are carried with the cover and of course are capable of being removed with the cover to facilitate cleaning of these parts as well as the body.

Among the other aims and objects of this invention may be recited the provision of a device of the character described with a view tocompactness, and in which the nunr ber of parts are few the construction simple, the cost of production low and the efficiency high. v

Other improvements and novel details in the construction and arrangement of the inn rious parts of the apparatus will be brought out more in detail in the description to. follow; which for a clear understanding of the invention should be considered in connection with the accompanying drawings forming a part hereofand wherein is dis closed for the purpose of illustration a convenient and satisfactory embodiment of the invention. It is to be noted in this connection that minor changes in the-construction and arrangement of parts may be made without departing fromthe principle of operation of the various The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a vertical sectional view of the improved churn;

Fig. 2 is a transverse section taken on line 2-2 of Fig. 1, and p Fig. 8 is a detail of a modified form of operating means.

Similar characters of reference are e1n ployed in all the above described views, to indicate. corresponding parts.

Referring now, more particularly, tothe accompanying drawings, there is provided a body 1 which may be formed of any suitable material and constructed in any desired shape in cross section, being in the present instance rectangular. Supporting legs 2 depend from the body and terminate in feet 3 designed to be secured to a suitable support by fasteners 4. A flanged cover 5 serves to ro1no' abl v close the'body and is formedwith opposed openings 6.

In order to agitate liquids withinthe body with a view toward making butter, etc, rods 7 are arranged through the openings 6 while hollowperforated piston heads 8'are pivotally connected to the lower ends of the rods and are in the present instance of a rectangular configuration being positioned in spaced relation to the respective side walls of the body and in close relation with the front and rear walls thereof as shown in the drawings. The sides of the piston heads or dashers are depressed to form onposed vertical grooves 9 for a purpose that will presently appear. A supporting rod 10 depends from the center of the cover and has the lower end removably arranged in a socket 11 mounted on the bottom of the body in the center thereof and serves to brace the cover.

To guide the reciprocation of the piston heads opposed pair of guide rails 12 have their upper flanged ends 13 secured by suitable fasteners 14: to the under surface of the cover and depend therefrom in spaced parallel relation to each other so as to be engaged by the adjacent grooves in the heads. The adjacent inner rails of each pair are arranged in closely spaced relation to and on opposite sides of the rod. A connecting plate 15 is now employed and is provided with a central opening 16 through the medium of which the plate is arranged about the rod while the respective ends of the plate are connected to the adjacent inner rails. By this arrangement it will be ap parent that the rod 10 incidentally serves to cooperate with the plate 15 in properly supporting the adjacent rails. The lower ends or" the outer rails are squared as at 17 and are remov ably mounted in sockets 18 secured to opposite points on the inner surface of the body so as to be properly supported and easily and entirely removed from the body when the cover is removed.

To actuate the piston heads in opposite directions, a shaft 19 is ournaled in bearings 20 formed on the upper ends of standards 21 which are in turn rigid with the upper surface of the cover. Thi shaft is formed with opposed crank portions 22 on which are pivotally engaged the upper ends of the adjacent rods 7. A pulley wheel 23 is rigidl mounted on the projecting end of the shaft and has trained thereabout a motion transmitting belt 24. also adapted to be operably connected with a suitable source of power (not shown).

In Fig. '3 of the drawing there is shown a slightly modified form of operating means which consists of a central standard 25 on the top of the cover designed to pivotally or swingingly support a handle lever 26 to which in turn is operably connected as at I 27 piston rods 28.

The mode of operation of the present invention may be reviewed as follows:--

Assuming that the parts have been assembled in the manner described and as indicated in the drawings, upon the rotation of the shaft 19 owing to the connection between crank portions 22 and the rods 7 the piston head 8 will be alternately reciprocated in opposite directions to agitate he liquid in the body. During this movement owing to the close arrangement of the piston heads with each other and with the walls of the body the liquid will necessarily pass 7 through the perforated hollow heads 8 so as to be efiectively agitated as is apparent. By removing the cover all of the parts With the exception of the sockets 11 and 18 will be removed from the body so that the latter may be easily cleaned after the liquid has been agitated or churned into butter, etc.

It i believed that in view of the foregoing description, a further detailed description of the operation of the invention is entirely unnecessary. Likewise it is believed that the advantage of the invention will be readily apparent.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof and it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limited sense. It is also to be understood that the language used in the following claim is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having thus fully described the invention what is claimed as new and desired to be secured by Letters Patent is A device of the character described including a body, a cover therefor, rods slidable through the cover, hollow perforated piston heads operatively connected to the lower ends of the rods and having pposed vertical grooves in the sides thereof, a bracing rod depending from the cover, a socket on the bottom of the body for removably receiving the rod, opposed pairs of guide rails depending from the cover and positioned so as to be slidably engageable by the grooves in the piston heads, sockets mounted on opposite sides of the body adj acent the bottom for removably receiving and supporting the outer guide rails, a cross bar disposed about the bracing rod and having the lower ends of the adjacent rails connected thereto 50 as to be supported thereby, and means operatively mounted on the cover and having the upper ends of the rods connected thereto for assuring of the reciprocation of the piston heads in the body.

In testimony whereof I allix my signature.

OSCAR I. HENSRUD.
